Posture Support Rod with Adjustable Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining good posture is challenging due to the physical demands of sitting for extended periods, which often leads to slouching, as it is the most comfortable position in modern society.
Innovation Solution
A support bar and strapping system that attaches to the user's back, utilizing length-adjustable straps and strategically positioned attachment points to prevent slouching by encouraging an erect posture, with a rigid support rod and padding for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid support rod is used to maintain erect posture, then posture correction effectiveness is improved, but comfort and ease of operation deteriorate due to pressure and rigidity
Solution Approach 1:
The patent applies this principle by using flexible straps instead of rigid structures to connect the support rod to the user's body. The straps wrap around the torso and distribute the mechanical load, providing both posture correction and comfort through flexibility and adjustability.
Solution Approach 2:
The patent applies this principle by incorporating padding between the rigid support rod and the user's back. This cushioning layer prevents direct pressure on the spine and surrounding tissues, reducing discomfort while maintaining the rod's structural support function.
2Reliability
If multiple straps are used to secure the support rod, then posture correction reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies this principle by dividing the support system into multiple modular straps, each responsible for a specific region of the torso. This segmentation allows independent adjustment of each strap and simplifies the overall structure compared to a single complex mounting system.
Solution Approach 2:
The patent applies this principle by making the straps length-adjustable, allowing the device to adapt to different user body sizes and preferences. This dynamic adjustability simplifies the design by using simple adjustable fasteners rather than custom-fitted rigid components.
3Reliability
If the support rod is pressed against the back to encourage erect carriage, then posture correction is improved, but physical discomfort increases
Solution Approach 1:
The patent applies this principle by placing padding between the support rod and the user's back before the rod exerts its corrective force. This cushioning layer distributes pressure and prevents harmful concentrated forces on sensitive areas while maintaining the rod's ability to guide erect posture.
Solution Approach 2:
The patent applies this principle by using flexible straps to distribute the pressure from the support rod across a larger surface area of the torso. This flexibility allows the system to adapt to body contours and reduces pressure points that would cause discomfort.

AI summary
An apparatus for fixing bad posture includes a support rod, multiple length-adjustable straps, and multiple strap-attachment points. The apparatus for fixing bad posture prevents the user from slouching by affixing the support rod to the user's back with the straps. The support rod is a rigid member that is placed against a user's back. The support rod has a rod body, a mounting face, and a bracing face. The rod body is the structural component of the support rod. The bracing face and mounting face are positioned on opposite lateral surfaces of the rod body. Thus positioned, the bracing face is pressed against the user's back when correcting posture. The strap-attachment points are connection mechanisms for the length-adjustable straps that are distributed along the length of the support rod. As such, each of the length-adjustable straps is attached to the support rod by a corresponding strap-attachment point.
